In addition to Doom related news, Doomworld also hosts the weekly /newstuff Chronicles reviews of new WADs uploaded to the idgames archive and a database of the archive with search, user comment, and mirror access capabilities. The site also provides informational resources about Doom and associated games, hosting of Doom websites, and a forum with over 10,000 registered users and 816,000 posts as of December 2009.

Doomworld provides a set of forums. Discussion areas are provided for Classic Doom, Doom 3, and Doom (2016), as well as the “Everything Else” general discussion forum and areas for discussion of news and hosted sites.

These "punishment"-oriented forums were formerly notable features of the site that were retired when Doomworld transitioned to its new forum software in 2017:

Instead of threads and posts being deleted, they were previously sent to "Post Hell". In contrast to the rest of the forums, Post Hell featured a bright orange theme, flashing imitation banner ad, obnoxious background music, and an animated flame effect at the bottom of the window. Fredrik Johansson was featured at the top of Post Hell.

Troublemakers were generally not banned outright from the site, but were instead temporarily “losered”. Losered people could only post in a single forum, “Losers”, which was invisible to normal users.

It was announced by Andrew Stine in early July of 2015 that AtomicGamer would close down by the end of the month and that plans were in place to backup and transfer all of the site's content to a new hosting arrangement in the hands of community members. As of July 25, the doomworld.com domain became intermittently unavailable due to a change made to AtomicGamer's DNS records. It was afterward fully re-established under Stine's control as an independent website. The site was temporarily available at an alternate doom.world domain name until transfer of the doomworld.com domain from Telefragged and sufficient DNS propagation were complete.

On March 13, 2017, to coincide with the 19th birthday of the site, Doomworld changed its backend codebase, moving from a heavily customized vBulletin 2.2.5 along with a collection of custom-written scripts to the IPS Community Suite.[5] The move was driven by the looming security issues in the old software, which was over 15 years old at that point, and it was decided that the amount of effort that would be required to fix the hundreds of potential vulnerabilities would be better used to configure a more modern backend software. The new software has support for social media features such as username tagging, notifications, a more robust private messaging system, status updates (to replace the semi-hidden "Blogs" subforum), integrated file uploading and sharing, and the ability to give "like"s to content.

The /idgames Database was also fully integrated into the new software; however, users protested that the new incarnation did not include all of the same features as the old version, most notably in its search functionality and a lack of full backwards compatibility with existing URLs. Within days of the change, the "old" /idgames Database was revived and the new version was demoted to "beta" status.

The move was met with mixed reactions, with many users appreciating the new features and functionality, including the "responsive" design that reformats the site for use on mobile devices. Others bemoaned the increased file bloat, the large amount of JavaScript now required for full functionality, and the increased page load times.
